Before placing a bet on a team, one must do a lot of research about that team. How that team has played in the past, how is their consistent performance, etc. These things determine our psychology. We often get very excited about our favorite teams, and at that time we place big bets on them. But we cannot win the rest. The reason for this is that we forget to check how strong the team is playing against that team due to being too excited. So in the case of gambling, we have to accept that it is not possible to win all bets. So there should be no overconfidence in any bet. Gambling winning should be left to luck.
At times too much analyses make one choose a wrong option too, gambling is a lucky game, even if you use fives days to analyze if you will that bet you will still win, but no one can down play the role of having a good analyzing before staking a bet. But be assured that there is no sure game, its all a prediction.
analysis can only reduce your lost, it will help you reduce your staking power and stake high on few games instead of picking many games. no serious gamblers will just pick a game and stake i know some do but its not guaranteed, this is just a prove that gambling is a lucky game for all that wants to try their luck.
